Project Overview
- Location: Parker, CO

Roof Condition
The existing low-slope roof on this Parker home in Douglas County was at the end of its life. The membrane was worn, seams had been patched, and the four skylight curbs were a leak risk. The home sits into a slope, so one roof edge meets the ground, which puts dirt and moisture right against the roofing.
- Worn membrane at the end of its service life
- Seams that had already been patched
- Four skylight curbs that were a leak risk
- One roof edge meets the ground, putting dirt and moisture right against the roofing
Evaluation & Approach
A full tear-off let the crew inspect the deck and bring the roof to R-30 instead of trapping old, tired material under a new layer. DensDeck gives the assembly its Class A fire rating, which matters on a wooded Parker lot, and it gives the membrane a firm surface that holds up to hail and foot traffic. Heat-welded TPO seams and welded clad-metal edges leave no glued laps to fail.
Why This Approach
- Full tear-off let the crew inspect the deck before the new roof went on
- Two layers of insulation bring the roof to R-30 LTTR
- DensDeck cover board gives the assembly its Class A fire rating, which matters on a wooded lot
- DensDeck gives the membrane a firm surface that holds up to hail and foot traffic
- Heat-welded TPO seams and welded clad-metal edges leave no glued laps to fail
- Regrading and RapidLock TPO at the edge that meets grade keep earth and water off the roof edge
Scope of Work
- Tear-Off: Tore off the existing roof down to the deck, which let the crew inspect the deck before any new material went on.
- R-30 Insulation: Installed two layers of insulation to reach R-30 LTTR.
